This is typical philosphical bullshit. It is the sort of thing that
gives philosophy a bad name among intellectuals. While philosophers are
doing this crapdoodle, mathematicians are doing real mathematics and
physicists are doing honest to goodness physics.

The main difference between mathematics and philosophy can be discerned
by studying how math and philsophy departments are equipped. In the math
department you have pencil, paper and wastebaskets. In the philosophy
department you have just pencil and paper.
